As time goes by, we get older and become more stubborn, but what is the deal here for being so stubborn? We basically block so many opportunities to update ourselves. Information comes and goes. We communicate, we learn from people, we get information from the environment, then we adjust ourselves and adapt the change. For people they are living at present have less complain than people having a mind that living in the past.
I see the privilege that being the youngest, because whatever my siblings are going through, I am the witness of it, so I learn from there. Unfortunately, most of them show me the dark side of human nature. It's sad when you see people trying so hard to pretend that they are good and well off, but actually its only a window dressing.
